RESUMO
AIM: Pulmonary embolism remains a leading cause of maternal mortality in developed countries despite developments in venous thromboembolism prophylaxis strategies. This study aimed to evaluate the effectiveness of our approach involving risk-scoring, D-dimer level assessment, and ultrasonography for obstetric venous thromboembolism. METHODS: This retrospective cohort study included women who delivered at 22-41 weeks of gestation in The University of Tsukuba Hospital, Japan between January and December 2020. Venous thromboembolism risk (determined according to Japanese guidelines) and D-dimer levels were evaluated within 20 weeks of gestation, 30-34 weeks of gestation, and during the pre-delivery period (36 weeks of gestation or any time before preterm delivery). Compression and color Doppler ultrasonography for lower extremity deep vein thrombosis were performed if D-dimer levels were ≥3.2 µg/mL (for those undergoing cesarean delivery, 1.0 µg/mL). RESULTS: Of 1026 women, 6 women had deep vein thrombosis during pregnancy and 1 during the puerperium period. Pulmonary embolism was not observed. The D-dimer screening result was positive for 8 women (2%) within 20 weeks of gestation (deep vein thrombosis was confirmed in 3 of them), 87 women (10%) (no deep vein thrombosis) at 30-34 weeks of gestation, and 367 women (36%) during the pre-delivery period (asymptomatic deep vein thrombosis in one). Based on the Japanese guidelines, 1%, 11%, 33%, and 55% of women had high, intermediate, low, and no postpartum risk factors, respectively. CONCLUSIONS: Our approach appears useful for antenatal venous thromboembolism screening in the first trimester. For postpartum prophylaxis, more cost-effective strategies are needed.

Introduction: Obstetric severe perineal laceration can frequently occur as a surgical site infection (SSI), which sometimes leads to rectovaginal fistula after repair. We encountered a rare case of a rectoperineal fistula 5 months after repair of a severe perineal laceration. Case presentation: The patient was a 39-year-old woman who underwent repair of a fourth-degree perineal laceration after vaginal delivery. Five months after primary repair, she presented with perineal swelling and pain followed by uncontrollable flatulence or passage of feces at the perineum, which was finally diagnosed as a rectoperineal fistula. Transperineal repair with fistulous tract excision was performed for the rectoperineal fistula. Closure of the rectum, perineal body, and vagina was performed layer-by-layer constructing a thick perineum to prevent anal dysfunction. The fistula was successfully closed, and the patient did not show any symptoms of fecal incontinence 6 months after surgery. Discussion: As the rectoperineal fistula might have resulted in SSI at the primary repair of the obstetric injury, the delayed occurrence of the rectoperineal fistula was unusual. A perineal approach should be performed for complete fistulous tract excision, reconstruction of a robust perineal structure, and preservation of anal sphincter function.
RESUMO
AIM: Post-partum hematomas are a serious obstetrical complication. Choosing treatments for post-partum hematomas is difficult, and the application of transcatheter arterial embolization remains unclear. We aimed to clarify the clinical characteristics, identify the treatment indications and create a treatment algorithm for post-partum hematomas. METHODS: Fifty-four patients with post-partum hematomas were enrolled. Hematomas were categorized according to location: upper vaginal, lower vaginal and vulvar. Blood loss, treatment methods and other clinical data were collected from the patients' medical records and analyzed retrospectively. RESULTS: Five, 19 and 30 patients had upper vaginal wall, lower vaginal wall and vulvar hematomas, respectively. All upper vaginal wall hematomas required transcatheter arterial embolization to control bleeding, and the average blood loss was 2473 ± 1689 mL. Most lower vaginal wall hematomas were treated surgically; however, two patients required transcatheter arterial embolization, and the average blood loss in these patients was much higher (2010 ± 1145 mL) than that in patients with lower vaginal wall hematomas (395 ± 316 mL). No patient with vulvar hematomas was treated with transcatheter arterial embolization. Two and four patients with vulvar and lower vaginal wall hematomas, respectively, were managed with observation. CONCLUSION: We created an algorithm for post-partum hematoma management. Post-partum hematoma location should guide treatment selection. Transcatheter arterial embolization should be selected for upper vaginal wall hematomas. Most lower vaginal wall hematomas are treatable with surgery, but transcatheter arterial embolization should be considered for hemostasis in difficult cases. Management with observation may also be possible for lower vaginal wall and vulvar hematomas.

AIMS: This study aimed to determine effective predictive factors for primary postpartum hemorrhage (PPH) among clinical blood parameters associated with coagulation and fibrinolysis and demographic characteristics. METHODS: We retrospectively studied 1032 women who underwent determinations of clinical blood parameters at gestational week (GW) 29-32 and GW 35-37 and gave birth to singleton infants at our hospital between January 2011 and December 2013. PPH was defined as estimated blood loss ≥700 mL. Multivariate logistic regression analyses were used to determine independent risk factors and odds ratios (OR) for PPH. RESULTS: PPH occurred in 104 of 1032 women (10%). Three blood variables, fibrinogen level <4.0 g/L (OR [95% CI], 1.96 [1.18-3.27]), antithrombin activity <85% of normal activity level (1.84 [1.05-3.21]), and D-dimer level >2.7 µg/mL (2.03 [1.29-3.19]) at GW 35-37, and three demographic characteristics, maternal age ≥35 years (1.75 [1.15-2.68]), BMI >28.2 kg/m2 on admission for childbirth (1.95 [1.20-3.16]), and previous cesarean delivery (2.77 [1.31-5.83]), were identified as independent risk factors for PPH. CONCLUSION: Among blood parameters, higher D-dimer levels and lower levels of antithrombin activity and fibrinogen in late gestation were independent risk factors for PPH.

OBJECTIVE: To clarify the effect of starvation due to hyperemesis gravidarum on the screening of gestational diabetes mellitus (GDM). METHODS: A retrospective study was undertaken of pregnant women who delivered at Tsukuba University Hospital, Japan, between October 1, 2010, and September 30, 2013. GDM screening was performed in the first trimester using the random blood glucose test with a cutoff value of 5.2mmol/L and in the second trimester using a 50-g glucose challenge test with a cutoff value of 7.8mmol/L. If the screening was positive, a 75-g oral glucose tolerance test was performed for a definite diagnosis. RESULTS: Among 2112 eligible women, 33 (1.6%) required hospitalization for hyperemesis; the remaining 2079 women formed the control group. In the first trimester, the positive GDM screening rate was significantly higher in the hyperemesis group than in the control group (13 [39.4%] vs 115 [5.5%]; P<0.001). Additionally, the positive predictive value was significantly lower in the hyperemesis group (23.1% vs 73.9%; P<0.001). In the second trimester, no significant differences were observed between groups. CONCLUSION: Hyperemesis gravidarum affects the positive GDM screening rate in the first trimester.

Adenomyosis is characterized by extension of endometrial glands and stromal cells into the myometrium. Here we proved that 'moesin' is a unique biomarker of adenomyosis. We selected two cases of adenomyosis that had been surgically resected and fixed with formalin. Proteins were extracted from the infiltrating adenomyosis lesions and normal endometrium by tissue microdissection. The extracted proteins were examined using a LC-MS/MS system and the expression profiles of each region were compared. Two hundred and sixty proteins were detected, among which 73 were expressed more in adenomyosis than in normal endometrium. Among these proteins, we focused on overexpression of moesin in adenomyosis. Expression of moesin estimated semiquantitatively using an immunohistochemistry score was higher in adenomyosis than in normal endometrium. In particular, moesin was significanly overexpressed in stromal cells of adenomyosis than in those of normal endometrium. Relative to normal endometrium, moesin was also overexpressed at the RNA level in 9 of 14 cases of adenomyosis and at the protein level in all 14 cases. We also detected activated (phosphorylated) moesin in adenomyosis lesions. The present findings suggest that moesin is characteristically overexpressed and activated in adenomyosis, and that moesin activation may be related to extension of adenomyosis in the myometrium.

Ovarian cancer immunoreactive antigen domain containing 2 (OCIAD2) has been reported to show cancer-specific expression in early invasive lung adenocarcinoma. OCIAD2 shows high homology with OCIAD1, which was originally immunoscreened from ascites of a patient with ovarian cancer and found to be a tumor-specific protein. Therefore, like OCIAD1, OCIAD2 is expected to show high immunoreactivity in ovarian tumors. In this study, we examined the expression pattern of OCIAD2 in 117 ovarian mucinous tumors, and confirmed that it was more highly expressed in borderline tumor and carcinoma (51/74 cases, 69%) than in adenoma (6/43 cases, 14%). The immunoreactivity of OCIAD2 in borderline tumor and carcinoma was more specific than that of OCIAD1 (adenoma, 21/43 cases, 49%), and more sensitive than that of CEA (borderline tumor and carcinoma, 35/74 cases, 47%). Like OCIAD1, OCIAD2 is a cancer-related protein and its expression level increases during the course of malignant progression and is thought to be a very useful marker for evaluating the malignancy of ovarian mucinous tumors.

We report a case of alveolar capillary dysplasia, wherein duodenal atresia was diagnosed during the third trimester. A 36-year-old mother was referred to our hospital for polyhydramnios at 31 weeks' gestation. Duodenal atresia was suspected from the ultrasonographic findings, which showed gastric dilation. Other findings noted were enlarged, highly echogenic lungs, a spherical heart and an increased lung-thorax transverse area ratio. A male infant was born at 37 weeks' gestation. The findings of serial radiography of the infant's upper gastrointestinal tract were compatible with the diagnosis of duodenal atresia; however, he developed persistent pulmonary hypertension of the newborn eight hours after birth and died at five days of age. The autopsy revealed alveolar capillary dysplasia and duodenal obstruction. We propose that the detection of duodenal atresia should prompt the physician to conduct a thorough ultrasonographic examination to rule out associated anomalies, such as alveolar capillary dysplasia, which can be detected by the presence of highly echogenic lungs.
